This invention relates to an improvement in the construction of a machine for cutting the croze or recess in the ends of barrel-Steves for receiving the odge-ofthe head ot' a barrel to secure it in place.

It consists ot an adjustable bench or table, on which the stave is laid to be crozed, to be raised or lowered as desired for giving the desired taper tothe croze, and provided with right and left-handed screws for clamping and holding the stave in the centre under the crozing-tool, togetherwitlx an arrangement of vertical' and horizontal slides, connectedwith a rod Working -in swivels, for raising and lo'werihg the cutting-tool to suit the required -circle ofthe croze.

By this arrangement oi' machinery thecrozing,r of barrel-stares is done with great accuracy and rapidity.

A is a long table, on which the stavesarelaid for crozing, the front end of which is hung on a-pivot-rod, a, supported at one end by a post, B', and at the other by a framefstandard, C. The rear end of the bench A is attached 4to a post, B', by a slide, Z1, which raises or lowers'the end as required, to give the desired taper to the croze in the stave lying lon it lengthwise. Bight and left-handed screws c c are set across the bench A, near its ends, which carry clampingblooks, d d', that'are moved to and from the centro to hold the stave in line eehtrally with the crozing-tcol or rotary cutterdiead D. The rotary cutter-head, or crozing-tool D, is provided with knives onthe sides and the periphery, to cut the. croze in size and sha-pc as desired. It is hung on a horizontal shaft, g, in bearings at the lower end of a vertical slide, E, one df which bearings is formed by an arm,A

L, that projects from the slide; and it receives its motion from a pulley, 7c. The vertical slideE works in ways formed by a horizontal slide, F, that moves on aslide-rest, G, fastened at one end to the standard C.

By this combination of vertical and horizontal slides, the cutter-head D admits of beingadjusted readily, and to have a compound motion when in operation; and for effecting the necessary movement in cutting the croze, the vertical slide E is connected by a rod, 1z,'\vith another adjustable vertical slide, H, Vwhich works in the upper part ofthe standard O, and is raised or lowered to snit the required circle. i The lower end ofthe rod n is threaded, and is fastened by check-nuts to a swivel-boss, p, placed on the top ofthe vertical slide E, ivhile the upper end of the rod n passes through a swivel-bcss, p', placed on the, end of an arm, H', projecting from the vertical slide H.

The vertical slide E ,may be fastened to the horizontal slide F by the set-screw q, for doing straight work;

and on the outer side of the slide F isa handle, m, to move it back and forth.

Having described our invention, we claim as new, and desire to secure by Letters Patent- 1. The cutter-head D, arranged in relation to the adjustable bench A, raised andlowered by the slide b, as herein described, for the purpose specified. i i 4 2. The compound vertical slide E and horizontal slide F, the connecting-rod n, the swivclspp', in which the rod Works, and the adjustable slide H in the standard C, combined, arranged, andoperatingsubstantially v as and for the purpose described,

The abve specification of our invention signed by us, thislOth day of April, 1867. 4
